Thermoelectric properties of icosahedral quasicrystals: a phenomenological approach

In this work, we introduce a phenomenological model describing the thermoelectric power of icosahedral quasicrystals. On the basis of a realistic model for the spectral conductivity, obtained from ab initio band-structure calculations [C. Landauro and H. Solbrig, Physica B 301, 267 (2000)], we deriv...
